Jarl manages Triton Submarine’s classification, certification, and statutory compliance program. He’s also a subject matter expert on acrylic pressure vessel technology. He has presided over significant advancements in the fabrication of acrylic pressure vessels for human occupancy, the quintessential feature of a Triton submersible. He’s also actively working to develop rules for the design by analysis (DBA) of acrylic pressure vessels for human occupancy (PVHOs). Previously, Jarl was responsible for classification of manned submersibles at the American Bureau of Shipping (ABS) spanning the mid-1980s to the mid-1990s, a time of explosive growth in the submersible industry, particularly tourist submersibles. He served on several technical committees involved in promulgating codes and standards for manned submersibles.
